  • Expensive replacement to Tetra Whisper Cartridges.
Size: 10 Pack Large
Well, no so long ago, a box of 12 Tetra Whisper 10g, 20g & 30g Lg.,Med., & Sm., Replacement Cartridges were anywhere from $8.96- $12.59. Now Their Double the price and you get 2 less Cartridges. On the upside, they come already assembled and the Fiber Mesh Filter part is more Dense. Meaning more small particles are being trapped and the Carbon is of good quality. However, I own 4 Aquariums, Tetra Whisper was the Cheaper of lesser brands, inexpensive to to purchase, but you have to put them together, which i didn't mind. What i do mind is, that Tetra & Marina, filter Media has more than Doubled, and are not even made by these Manufacturers anymore, with the Exception of Marina Slim Cartridges, and they have increased recently from 9 3pk Cartridges from as low as $6.86 to $16+, and yes they do have another manufacturer that make these same size cartridges, but their even more expensive. Marketing and Targeting Maybe? In all this, is a very good Quality, if not better than the original Tetra Whisper Filter replacements, on the account, they come assembled and you can see a small significant clarity in your Aquarium, however they don't last as long, do to the more waste it traps. Tip: On all of the filters i mentioned above, if you rinse them out thoroughly with warm water and place them in the Sun for a full 24hrs. They recharge and are good to go. I've gotten 3 time the use out of each 1, however the 3rd time, doesn't last that long. In the End, i have a Tidal 75 that i can use, but too many issues, not do to the product. I hope this Review has been helpful and informational, to keep your Aquariums clean and Fishies Happy. I've been an Aquarist now for over 40 years. If you have anymore questions or need answers, Amazon will be quick to notify me, to answer a fellow colleague, who has purchased or is going to purchase, any products that I have bought and used, and still using today. 👍😎✌ ... show more

  • Great substitute for Tetra filters

  • Nice filters.
Size: 6 Pack Large
I found these on Amazon and they work great. I normally buy from Amazon the kit that you have to assemble each filter when replacing them. I ended up finding these on Amazon and I don’t have to assemble them. All I have to do is stick them into my filtration system and done. This makes cleaning the tank quite a bit easier ... show more
